|table-ref| (hashtable access) speed being non-deterministic would be all
fine as the average access speed should remain constant.
To preserve the possibility of fully deterministic behavior, maybe double
hash attack protection by random seeding could be... on by default but can
be disabled via a key argument, or, off by default and can be enabled via a
key argument, something like this?
